refactor(corrections): point audit-enforceability and retro codify references at /corrections:codify #11962

Parent: #11129

Slice 1 of 4 of #11129. The lane's patch was 518,254 bytes against the 262,144-byte cap
(run 41281439308).
This slice repoints references in every plugin except review and session-flow, plus the two generated
enforcement-ladder copies there; slices 2 and 3 delete the two surfaces. /corrections:codify already
takes a findings file and PR review comments (#11128).

Decisions that bind this slice

• feat\(corrections\): absorb retro codify and /review:audit-enforceability into /corrections:codify and remove them - part 2 of 2 #11129 is part 2 of feat(corrections): absorb retro codify and /review:audit-enforceability into /corrections:codify and remove them #11121, split at intake under Q93 (the intake split comment on feat(corrections): absorb retro codify and /review:audit-enforceability into /corrections:codify and remove them #11121).
• From feat(corrections): absorb retro codify and /review:audit-enforceability into /corrections:codify and remove them #11121: every reference moves to /corrections:codify. In docs/upstream/ records and in
  corrections' own files, reword the reference to the current name rather than deleting the record.
• Split by hand by the Issue Triage session after the issue lane's scan refused each run's patch
  as too large. No owner decision is claimed for this split.

Task list (from #11129, line 1, scoped to this slice)

• Replace each /review:audit-enforceability and retro codify reference (/session-flow:retro codify,
  `/session-flow:retro` codify, `retro` codify) with /corrections:codify (and its findings
  or reviews action where the old text meant that input) in: plugins/architecture/ (README.md,
  skills/improve/SKILL.md, actions/boundaries.md, evals/evals.json, research/boundaries/README.md),
  plugins/code-tidying/skills/dissolve-comments/ (SKILL.md, evals/evals.json),
  plugins/corrections/skills/codify/SKILL.md (Boundary, ## Next, and line 175),
  plugins/coupling/skills/reduce/ (SKILL.md, evals/evals.json, reference/remediations.md),
  plugins/debugging/skills/debug/ (SKILL.md, evals/evals.json),
  plugins/harness-config/skills/audit-automation-gaps/SKILL.md,
  plugins/improvement/skills/find/ (context/unattended.md, evals/evals.json),
  plugins/toolchain/ (skills/ratchet/SKILL.md, probes/ratchet.json, evals/ratchet-zero-lands-rule/samples/skill-fired.json),
  plugins/work-items/reference/tracker-seam.md, docs/upstream/cursor-pstack.md, docs/upstream/mattpocock-skills.md.
• Repoint the links and line citations in docs/upstream/cursor-pstack.md (lines 73, 95 and 111) that
  target plugins/session-flow/skills/retro/context/codify.md and
  plugins/review/skills/audit-enforceability/SKILL.md, which slices 2 and 3 delete.
• Edit docs/contracts/enforcement-ladder/README.md (the /review:audit-enforceability and
  /session-flow:retro codify rows) and run scripts/sync-shared-copies.sh, which regenerates all five
  copies, those in plugins/review/context/ and plugins/session-flow/skills/retro/reference/ included.
  Never edit a copy by hand.
• Every ## Next that named either old surface names /corrections:codify.

Out of scope

• Deleting /review:audit-enforceability (slice 2) or retro's codify mode (slice 3), and any other file
  under plugins/review or plugins/session-flow than the two generated enforcement-ladder copies.
• audit-sessions style; chat and meeting sources (out of scope in feat(corrections): absorb retro codify and /review:audit-enforceability into /corrections:codify and remove them #11121).
